Here's an update to the block layer and SCSI data integrity code. There are a whole bunch of cleanups, some as a result of the work that Kent did to the block layer a while back. A bunch of dead code is removed, mainly the tagging functionality that nobody ended up using. There's also some prep work for the copy offload patches (separate series) that like the integrity code rely on being able to store additional information in each bio. The new functionality introduced is: - Exposing whether disks are formatted with PI in the bdev integrity profile so we can reliably distinguish between DIX Type 0 and DIX Type 1 - Allowing the choice of checksum and tag checking to be specified on a per-I/O basis - Data integrity specific error numbers - Moving the T10 protection information specifics to lib/ so that non-sd drivers can benefit from them - Adding support for a subset of DIX1.1 to the scsi_cmnd flags. These flags instruct the HBA drivers how to set up the protected transfer Documentation/ABI/testing/sysfs-block | 9 Documentation/block/data-integrity.txt | 54 ----- block/Kconfig | 1 block/bio-integrity.c | 273 ++++++-------------------- block/blk-core.c | 12 + block/blk-integrity.c | 102 ++++++--- block/blk-merge.c | 6 drivers/md/dm-mpath.c | 9 drivers/scsi/Kconfig | 2 drivers/scsi/scsi_lib.c | 30 ++ drivers/scsi/sd.c | 56 ++++- drivers/scsi/sd.h | 4 drivers/scsi/sd_dif.c | 337 +++++---------------------------- include/linux/bio.h | 62 ++++-- include/linux/blk_types.h | 14 - include/linux/blkdev.h | 54 ++--- include/linux/crc-t10dif.h | 5 include/linux/t10-pi.h | 28 ++ include/scsi/scsi_cmnd.h | 29 ++ include/uapi/asm-generic/errno.h | 11 + lib/Kconfig | 7 lib/Makefile | 2 lib/t10-pi.c | 164 ++++++++++++++++ 23 files changed, 627 insertions(+), 644 deletions(-) -- Martin K.
